sonofsam 5 Posted October 31, 2005 Evening all well i have sourced a be3 t/d gearbox..is it worth buying for my 2.0l turbo project..is it worth £125 delivered thats the question..it does include speed sensor too cheers sam. Share this post Link to post Share on other sites
Hilgie 16 2 Cars Posted October 31, 2005 I wouldn't use it as it's way too loooooong..... BE3 1.9 GTi boxes are great though. Share this post Link to post Share on other sites
TEKNOPUG 3 Posted October 31, 2005 It's about 10-15% taller IIRC. Should work quite well - certainly will be better on Motorways! Although the 1.9 box works fine. Share this post Link to post Share on other sites
sonofsam 5 Posted October 31, 2005 Thankyou fellas.1.9 box should be alot cheaper too i have a 1.6 be3 at the moment and sent a perfectly good 1.9 box down to the scrap yard in the green machine..doh doh doh sam. Share this post Link to post Share on other sites
Guest davetibbs Posted October 31, 2005 I liked the TD box I had on my 405 2.0 Turbo - but it hit the limiter just before 60 in second, which meant more gearchanges than necessary on 0-60 trials! It was good because the first two gears were really short to help the sluggish diesel get up to speed, then the higher gears were longer which was good for cruising. Not sure a BE3 TD box is worth £125 though!!! I've seen them on eBay for £30 Share this post Link to post Share on other sites
TEKNOPUG 3 Posted October 31, 2005 I think that it's the D boxes that are really long. I'd recommend a hybrid box - 1.9 with TD FD Share this post Link to post Share on other sites

TEKNOPUG 3 Posted October 31, 2005 I spent a lot of time looking into this and doing the calculations. Using the TD FD, you will keep the 1.9 gear spacing (long 1&2 short 3/4/5) but extend all the ratios by 10%. Therefore 5th would change from 20mph per 1k to 22mph per 1k. Should allow you to keep in the power and hold the revs for a little longer. You won't have much need to rev the engine past 5750 with a turbo. Share this post Link to post Share on other sites

205turbo 32 2 Cars Posted October 31, 2005 (edited) i'm using a D box in my turbo, I always felt like i was in 4th gear when it was in 5th on the 1.9 box, theres more than enough torque to use a high ratio box Edited October 31, 2005 by 205turbo Share this post Link to post Share on other sites

Although 80-120mph in fifth never fails to put a smile on my face Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted October 31, 2005 I might have an ideally suited gearbox for this use that I was thinking of using in my 2044cc engine (should it ever see the light of day). A 405 BE3 Mi16 with 1.9 FD so that 1 & 2 are the same as standard 1.9 (near enough) & then 3rd, 4th & fifth are longer. Compare here Graham. Share this post Link to post Share on other sites
Banjo 1 Posted October 31, 2005 pugtorque what sort of rpm would that combo be doing at 70 roughly? Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted November 1, 2005 pugtorque what sort of rpm would that combo be doing at 70 roughly? Approximately 2900rpm according to Zoldama's gear calculator. Graham. Share this post Link to post Share on other sites
sonofsam 5 Posted November 2, 2005 thanks for all your help on this everyone.i have bit the bullet and bought the overpriced td box,got another quote this morning for one and it was around the same sort of price.so decided to go with it. looking forward to stripping it down as i have never done it before,going to be a great little winter project for when its to rainy,dark and cold to work on the drive.hopefully the td fd will pay off in the end sam.

Pug_101 0 Posted April 16, 2006 Sorry for hijacking this thead i've just got 1 question for my project, on a similar theme. Ok if the final drive can be changed between these boxes (pugtorque's link) are the other gears also swapable? Interested in changing the first gear and final drive for my project. Thanks Share this post Link to post Share on other sites
Anthony 1,003 Posted April 16, 2006 Ok if the final drive can be changed between these boxes (pugtorque's link) are the other gears also swapable?Interested in changing the first gear and final drive for my project. Yes, but to change anything except 5th is a 'box stripdown job (although you'd be doing that anyway to swap the final drive over) Share this post Link to post Share on other sites
Pug_101 0 Posted April 16, 2006 Yes, but to change anything except 5th is a 'box stripdown job (although you'd be doing that anyway to swap the final drive over) Don't think I will need to change 1st gear now. Think I've spotted a problem in Zoidalma's gear program: Zoldalma The Mi16 405 gearbox does not match the gear ratio for 1st gear as shown in pugtorques first link: techgearboxUK Which is correct? or have I missed somthing of course they maybe different gearboxes, but without part numbers I can not tell. using techgearboxUK's ratios on the 405 Mi16 gearbox with a 205 1.9L GTi final drive gives me @ 3000rpm with 185/55 R15 tyres: 1st=19 std 205 1.9L GTi 1st=19 2nd=30 std 205 1.9L GTi 2nd=30 3rd=44 std 205 1.9L GTi 3rd=41 4th=58 std 205 1.9L GTi 4th=52 5th=74 std 205 1.9L GTi 5th=65 This seems prefect for my needs. Same low down pull with better motorway ratios. Thanks Share this post Link to post Share on other sites
